-To all whomt't may concern.'

Be it known that we, JOSEPH BIANUHI and Loursn A. BIANCHI, citizens of the United States, and residents of the city of Chicago, county of Cook, and State of Illinois, have .invented certain new and luseful Improve- .ments in Oil Burners, of which the followl provision of introducing air into the burner so as to increase'the intensityof the heat i and at the same time create a draught so that there will at alll times be a uniform preferred circulation of the air through the burner.

Other objects will appear hereinafter. The invention consists in the combinations and arran ements of Iparts hereinafter described and c aimed. The invention will be best understoodvby reference to the accompanying 'drawings forming apart of this specification and in which,

Fig. 1, is a sectional v1ew. of a burner' embodying the invention; l

Fi 2, is a sectional view taken substantially on line 2--2 of Fig. 1, and

Fig. 3, is a fragmentary view of the wick embodied` in the Invention.

Referrin to the drawings showing the Iorm of construction A indicates the .burner embodying the invention comprising a hollow bod 10 having a hori- `zontal partition 11 rovlded with a central opening 12 surroun ed by an annular flange 13. The partition 11 divides the body into two compartments one above the other indicated at 14 and 15. Communicating with the lower compartment 15 is a cavlt 16 formed in alateral extension 17, locate ad- 'acent the bottom of the body, the cavity 16 `being adapted to permit the introduction of air into the compartment 15. Communicating .with the compartment 14 is a supply pipe 18 having an inlet located 1n the side wall of the body below the edges 20 of the annular fiange 13, for the delivery of fluid to the compartment. Surrounding the inner side walls 21 of the compartment 14 is an asbestos wick 22 having a portion covering rthe inlet 19 so that Athe wick will readily absorb the fluid passing into the compartment 14. The surfaces of the wick adjacent the walls 21 are covered by a perforated band 14, the purposes of which are to permit penetration of the iuid into the Wick and also to permit the fluid to iow between the band and the Wall andl penetrate into the wick through the various perforations of the band. A cap 23 having a central opening 24 and openings 25 radially disposed about the central opening 24 is carried by the annular flauge'l, the cap 23 being an inverted, dish-shaped member so that the radiallyfdisposed openings 25 will discharge the air fromthe compartment 15 in diverged directions with respect to the air-passing lthrough the central opening 24, the direction of the air through these open- 'ings 24 being indicated by arrows in Fig.. 1.

It will be seen that by forming the cap in the manner above described that the flame of the burner is spread .outwardly so as to cover a large surface. l

A closure 26 is provided for the open top 27 of the body and is provided with a cen tral opening 28 of a vdiameter substantially equal to the outside diameter ofthe annular flange 13, the peripheral edges of the closure 26 being set in recesses 28 formed in the sidewalls 29 of the body. In use, the asbestos wick-22 is ignited in any `mannerdesira-ble and the heat radiated therefrom .and the fiame thereof passes through the opening 28 of the closure 26 and at the same time air is being introduced into the air compartment 15. through the cavity 16 and isdrawn up through the opening 12, and the several openings of the cap 23 commingling with the'fiame ofthe wick spreading the flame so as to cover a large surface of thel apparatus. with which the burner is used; this yspreading of the flame is accomplished" as stated, by diverging the incoming air in several directions through the radially disposed openings 25.

The burner may be of an other configuration than that slw an of any size or proportion without destroying the utility of the invention, it being borne in mindthat by the construction of a burner-as herein set forth the area of the surface heated by the burner is greatly increased by the provision -of lthe several o enings formed in the dish-shaped cap 23. t will also be apparj air compartment, as it passes up through the opening 12 will be heated so that by the time the air passes through the several openings of the cap the air is of a higher ytemperature thanthatpassing through the cavity into the compartment 15. Still further it will be apparent that as the heated air 'passes with the llames through the closure opening a suction will be provided as the incoming air is introduced through. tl.e opening from below the combustion compartment and will assure a uniform circulation of air. A

While we have illustrated and described the preferred form of construction for car- .,rying our invention into effect, this is capable of variationand modification without departing from the spirit of the invention. We, therefore, do not wish to be limited to the precise details of construction set'forth, but desire to avail ourselves of such variations and modiications as come within the scope of the appended claims.

Having described our invention what we claim as new and desire to secure by Letters Patent is:

1. A burner of the class described including a bodyhaving a partition dividing the body into two compartments, an extension having a cavitv'communicating with one of said. compartments for the .introduction of air thereto, flanged means formed in said partition providing an opening, and an inverted dish-shaped perforated cover mount.- ed overlsaid opening lto direct the air from the air compartment in various directions in the other compartment.

2. A burner of the class described including a hollow7 body having a cross partition through the other compartment and commingle with the iames 'of the burning fluid.

3.v A burner of the class described including a body having a partition dividing the body into an upper and lower compartment, said partition having a central opening surrounded by an annular flange extending into the upper compartment, an extension havmg a cavity communicating with the lower compartment for the introduction of air thereto, and a perforated dish-shaped member carried by the annular flange adapted to direct the air in various directions passing from the'lower compartment through the upper compartment.

4. A burner of theV class described includ-y ingl a body having a partition dividing the body into an upper and lower compartment, said partition having a central opening surrounded by an annular flange extending. into the upper compartment, a wiclrmounted in the upper compartment, an extension having a cavity communicatingl with the lower compartment for the introduction of @air thereto, and an inverted dish-shaped perforated member carried by the flange adapted to direct the air passing from the lower compartment through the upper compartment in various directions..

5. A burner of the class described including a body, a partition dividingthe .body into an upper and lower compartment, the lower compartment having an extensionprovided with a cavitfor the introduction of air thereto, there eing an opening in the partition surrounded by anannular flange, a dish-shaped member carried by .the flange and provided with a centalopening -and radially disposed openings about said central opening, a wick arranged'in the upper compartment, a closure member for the upper compartment having an opening `above the opening of the partition.

In testimony whereof we have signed our names to this specification in of two subscribing witnesses,
